The scandalous singer caused a stir by prancing around with just a Yankees shirt covering her lacy lingerie at the Subway Series loss, but a source with the team exclusively told RadarOnline.com that she was barely dressed when she turned up for the game.

“She showed up in a bra, panties and fishnets. We supplied her with a Mariano Rivera jersey to wear so she could sit outside of the suite,” revealed the Yankees’ insider. Lady G unbuttoned the shirt and tied up the bottom so that her sexy underwear was still clearly visible underneath.

Despite her drunken antics, the Poker Face pop star will be allowed back for future games, the New York Post reported on Monday. “She’s not banned,” from Yankee Stadium or the VIP area, said the team’s GM Brian Cashman. “She didn’t do anything wrong.” He is blaming his own employees for letting her into the restricted area and will step up enforcement of the existing clubhouse rules.

Cashman explained that no celebrities, not even basketball legend Michael Jordan, should be allowed into the clubhouse after a loss. “That was the wrong time and the wrong place,” he said, adding that there are other areas places in the Stadium that the players can interact with celebrities.

Gaga had better hope that the Yankees win the next time she goes to see them play – then she might be allowed to celebrate in her usual outrageous style!
